CollectD goes off

Buongiorno everyone,
i have succesfully installed CollectD to get some stats to my InfluxDB. I have noticed that some time pfSense shutoff CollectD, i have already try to addcollectd_enable=YESin the rc.conf but seems not work, the file says to not modifing anything… I have also added shellcmd package to run CollectD using this command```
/usr/local/etc/rc.d/collectd start
